virtio-serial: Don't override some words

term-io.fs already overrides "emit", "key" and "key?" with its own version:

- "term-io-emit" calls the "write" method of the "stdout" instance, which
  then calls "virtio-serial-putchar"

- "term-io-key" calls the "read" method of the "stdout" instance, which then
  calls "virtio-serial-getchar"

- "term-io-key?" calls "serial-key?" if the device is a serial device, which
   is the case here and we already override "serial-key?" with
   "virtio-serial-term-key?".

It thus looks weird to rely on these shortcuts. Especially, when IOMMU is
enabled, we need a valid instance in "dmap-map-in" and going through
"term-io-emit" buys us that.
